I am the new saftey officer at a small manufacturing plant---I was asked to look into the requirements for testing the electrical outlets in our plant. Can somebody provide me with a reference that I can use for this.
For the most part, outlet testing is purely a preventive maintenance function. Schedule it as you see fit.
Typical GFCI outlets require testing on a once per month basis or prior to every use. There are now some self-monitoring GFCI outlets that remove that requirement.
